PROTRONIX ADS-RH-D Duct Mounted Relative Humidity Sensor User Manual
ADS-RH-D is used to control ventilation, heat recovery and air conditioning systems by measuring relative humidity in the air duct.
- relative humidity measuring
- analog voltage / current output
- output relay
- fully calibrated
- long-term stability
Description
ADS-RH-D is a capacitive relative humidity (RH) sensor.
It is equipped with an output relay with adjustable switching level and with
analog 0-10V voltage / 0- 20mA (4-20mA) current output. The measurement is
performed periodically after about 8s.
Based on these measurements it is possible to directly control the ventilation, air conditioning and heat recovery units.

Output voltage/current dependence graph
Internal layout
Relay switching level adjustment trimmer
- turn to the left to decrease the relay switching level of RH, the relay will switch at lower RH level
- turn to the right to increase the relay switching level of RH, the relay will switch at higher RH level
To avoid fast relay switching around the adjusted level the hysteresis of 15% is added automatically.
Voltage / current output petting – jumper JP1
-
Jumper in position U = voltage output.
-
Jumper in position I = current output.
Current output petting – jumper JP2
-
Jumper fitted = output 4-20mA.
-
Jumper not fitted = output 0-20mA.
LED indication
Blue
- relay contacts closed = indication is on
- relay contacts opened = indication is off
LED indication setting – jumper JP5:
-
Jumper fitted = LED enabled.
-
Jumper not fitted = LED disabled.
Connection example
Installation
If you connect other devices to the same AC power source as the ADS sensor, it is necessary to meet GND wiring of all analog inputs and outputs, as well as power wires.
